NILS NILSON, OF MAPLE PLAIN, MINNESOTA.

- VEHICLE-SPRING.

SPECIFICATION formingpart of Letters Patent No. 226,540, dated April 13, 1880.

Application filed February 14, 1880.

To all whom it may concern:

Be it known that I, NiLs NILsoN, of Maple Plain. in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Springs for Vehicles and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin gs, which form a part of this specification, and in which Figure 1 is a side elevation of a wagon-box Fig. 2 is a bottom plan. Fig. '3 is a front elevation, and Figs. 4, 5, and 6 are detail views.

Similar letters of reference indicate corresponding parts in all the figures.

The object of my invention is to construct a spring, or rather a combination of springs, adapted to all classes of vehicles, which shall not be liable to break under a heavy load or on rough roads, can be constructed at comparatively small cost, and enables the wagon box or body to be adjusted (raised or lowered) vertically by means of a simple system of levers, substantially as hereinafter more fully described.

In the drawings, A isthe wagon box or body, which maybe of any suitable construction. Upon the bottom of the box, at the rear end, is secured a pair of straight fiat springs, B B, and at the forward end a similar pair, B B, the inner ends of each pair overlapping each other.

The outer ends of the rearmost springs B B are made with eyes I) b, which connect by means of a short link with the inner ends of a pair of arms, 0 (J, rigidly affixed crosswise upon a flattened spring-bar, D, each projecting end of which is provided with a fixed sleeve, (1', and spur-disk E, as shown in the perspective detail view, Fig. 4.

F F are arms or levers, the head of each of which is perforated and provided with a circular notched recess, f, fitting the spur-disk E upon the ends of bar D, the sleeve d of which is inserted into the central perforation of the lever-head, which is fastened down adj ustably upon disk E by a nut, 0. (See Fig. 6 of the drawings.)

hinged upon the rear axle, G, upon the under side of which are also hinged two arms, H H, the inner ends of which are pivoted in the lower ends of the hangers I I, through which the rounded ends of bar D are inserted, thehangers I I being braced by rods h h.

K is the curved end spring, which is secured by its arch or middle upon the wagon-box, and hinged or flexibly connected at each end to the rear ends of the cross pieces or arms 0 0.

Under the front part of the box is a similar arrangement of sprin gs and levers, (denoted by the letters B B, U, K, F F;) but the rod D, which connects arms 0 O and the adjustable levers F F, is here madein two sec tions, which are united at their middle by a sleeve, L, (see Fig. 3,) so that its ends may turn independent of each other. Instead of the brace-rods h 71, there is a single bent rod, 2', secured midway under the box and crossing the sleeve L of rod D D. In the elbow of rod 2' is pivoted an arm, M, the forward end of which is hinged upon the under side of the middle part of the front axle, G, (forming an adjustable or yielding brace for the axle and its bolster N by means of a bolt, n, which has a nut, '11., at its upper end, and is forked or bifurcated at its lower end, 42 to receive the end of the hinged arm or brace M. This construction permits axle G to swing freely on its bolt or pivot n in turning the wagon.

As above stated, one of the objects of my invention is to raise or lower the vehicle-body, which is effected by loosening and removing the nuts 6, then removing the sockets f of the levers F F from the spur-disks E of the rods D D, when,by elevatingor lowering the body, as desired, and again inserting the spur-disks E into the sockets f, or rather fitting the latter upon the disks, whose teeth will hold the parts as adjusted, the adjustment is accomplished. The nuts 0 are now screwed upon the screw-threaded portions of the rods, and the parts will be firmly secured together, as before.

The function of the compound arrangement of springs and levers is apparent, or will be understood from the following.

The arrangement and combination of the side springs, B B B B, with their respective end springs, K K, by means of the pivoted The outer or rear ends of levers F F are connecting-arms G O O 0, cause them to bear in opposite directions, or against each other, so as to mutually support and relieve each other of excess of strain. When weight is placed upon the vehicle (as the bearing comes on the middle of the springs and the hangers I) the shafts D D are rotated in their bearings in the hangers, and the levers O O are moved upon their centers and operate upon the ends of the springs, thereby producing an easy movement.

Having thus described myinvention, I claim and desire to secure by Letters Patent of the United States l. Thecombination of the side springs, B B, of the body or box A with the pivoted arms or levers 0 O, rods D I), levers F, arms H, hangers I, and springs K K, as set forth.

2. I11 combination, the vehicle box or body A, provided with the side springs, B B B B, and hangers II I I, rods or bars D D, having e'rosspieces G 0 0'0 and spur-disks E, adjustable levers F F F F, provided with recessed heads to fit the spur-disks E, nuts 0, rear axle, G, and frontbolster, N, substantially as and for the purpose herein shown and specified.

3. The combination of the vehicle box or body A, provided With the front side springs, B B, fronthangers, I. I, and central bent rod or yoke, 'i, sectional rod D D, provided with the sleeve or coupling L and arms or crosspieces 0 0, adjustable levers F F, bolster N, pivoted axle G, and yielding brace-arm M, substantially as and for the purpose herein shown and set forth.

4. The combination of the vehicle box or NlLS LsoN.
